报告简介:
Plasticity, fatigue, and fracture of materials are usually initiated by local deformation processes. Detecting and understanding the underlying mechanisms is the key to improve the mechanical performance and lifetime of miniaturized materials and also of macroscopic materials. In this presentation, experimental methods to perform quantitative nano-/micromechanical and tribological tests for complex and miniaturized materials will be introduced. The plastic flow law of metal materials and the influence of twin boundary will be analyzed. In addition, a new kind of micromechanical testing method,micro wall scratch experiment,will be introduced in detail.
